摘　　要：针对于木薯收获机械的特点,采用SolidWorks软件对其切割装置进行结构设计,将模型导入ADAMS软件中进行运动仿真。仿真结果表明:切割器最大位移为1 190mm,最大切割速度为30.008mm/s,切断一根茎秆需用时0.253s,证明所设计切割装置的运动状态与物理样机相符,满足设计要求,并且得到了木薯茎秆在切割装置作用下的一系列运动曲线;对木薯茎秆进行试验台切割试验,试验结果表明:木薯茎秆切割主要断裂形式为一刀切割、重割和切割后碰裂,其中漏割碰撞断裂的统计频数小于3%;经过初步分析,影响木薯茎秆切割质量的主要因素为切割器的结构参数和工作参数,为木薯收获机械切割装置的研制提供一定的理论依据。According to the characteristics of cassava harvester,using SolidWorks software to design the structure of the cutting mechanism,the model is imported into ADAMS software for motion simulation.The simulation result shows that the maximum displacement of the cutter is 1 190 mm,the maximum cutting speed is 30.008 mm/s,cutting a stem needs 0.253 s,and it proves that the motion of the cutting mechanism matches the motion of the physical prototype,it meets the design requirements;and it obtains a series of motion curve of cassava stalk cutting.Test bench is carried out having cutting experiment on the cassava stem,the results showed that the main fracture mode of cassava stem cutting are one size fits all cut,repeat cutting,touch crack after cutting,and the frequency of touch crack after cutting is less than 3%;After a preliminary analysis,the main factors of influencing the quality of cassava stem cutting are the structure parameters and the working parameters of the cutter,it provides a theoretical basis for the development of cassava harvester cutting mechanism.
